Christian Moore hit for more than the cycle and Dylan Dreilling delivered the walk off hit as Tennessee came back from a 3-run deficit in the bottom of the ninth to win the opener of the College World Series.
Trailing Florida State 11-8, Kavares Tears opened the bottom of the ninth with a triple to centerfield. He scored on a sacrifice fly down the rightfield line by shortstop Dean Curley, but top-seed Tennessee was still down by two.
Backup catcher Cannon Peebles took a walk, but catcher Cal Stark popped up to put the Vols just an out from starting the series in the losers bracket.
But it brought to the plate Moore, who had already become just the second player in Mens College World Series to hit for the cycle, including a 440-foot blast over the centerfield fence. This time he doubled down the leftfield line, putting Vols on second and third.
Blake Burke hit a liner over the pitcher's head to tie the game, sending Vol fans into hysterics.
Clemson transfer Billy Amick kept it going with a single to left before Dreiling's game-winning heroics.
The Seminoles got on the board first with a bases loaded walk in the first inning.
Moore opened the game for Tennessee with a triple. He was knocked in by Burke, who in turn scored on a Dreiling hit for a 2-1 Vol lead.
Moore doubled to left in the bottom of the second, scoring Stark who had walked. Moore came around on a throwing error to first by highly regarded Florida State starter Jamie Arnold on a Burke hit. Tennessee led 4-1.
But Florida State struck for six runs in the top of the third, aided by a Burke error at first, to lead 7-4. A Jaime Ferrer home run the next inning made it 9-4 and left Tennessee a big hole to dig out of.
Tears homered to right in the bottom of the fifth, pulling the Vols to 9-6. A Moore homer in the sixth made it 9-7.
A Marco Dinges double in the seventh plated two runs, pushing the lead up to 11-7.
Dreiling knocked in Burke in the eighth to get to the 11-8 count.
Tennessee had 18 hits on the night to 13 for the Seminoles.
Nate Snead, who pitches the last 2.1 innings, got the win.
Coach Tony Vitello used six pitchers, including starter Chris Stamos, who soon yielded to AJ Causey.
